Powdered limestone is used as a filler in paper, paint, rubber, and plastics. Crushed limestone is used as a filter stone in on-site sewage disposal systems. Powdered limestone is also used as a sorbent (a substance that absorbs pollutants) at many coal-burning facilities. Limestone is not found everywhere.Surfaces | Rails-to-Trails Conservancy,Because crushed stone can be made of nearly any type of rock, including limestone and sandstone, it is one of the most accessible trail surface types. Soil Cement. Soil cement is a mixture of pulverized native soil, Portland cement and water, rolled and compacted into very dense surface.
Cutting, crushing and loading rock in a single operation,
CUTTING, CRUSHING AND LOADING IN A SINGLE OPERATION The mining material is cut, crushed and, if re-quired, loaded straight into trucks or dumpers in a single operation, thus dispensing with conventional primary crushing in an additional work step.

This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogenCrusher - an overview | ScienceDirect Topics,Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher
